The Sandbox has been going strong on the App Store ever since its release, and it doesn't really seem to be losing any momentum. The new update includes a few notable additions such as a free campaign made up of user-created content, the ability to search user-created worlds by category (pixel art, music, etc), new daily quests, and prism and laser elements. Oh, and controllable avatars (including a ninja). So on top of all the arting and physicsing, users will also be able to create their own custom platforming stages.
